Answer:
$63
Step-by-step explanation:
1. Norachai and 6 of his friends = 7
2. Each of them paid $9
3. 7x9=63
4. The total bill was $63
First what you wanna do is get y by it’s self. To do that is to first add 5 on each side.
-5+3y=-4
+5 +5
3y= 1
Than you divide 3 on each side and it would give you y=1/3 if it’s a fractions problem but if you looking for decimals you would have to divide 1 by 3 which gets you .33333333.
The store which offers the greater discount is store B.
<h3>Discount</h3>
Store A:
First week = 10%
= 10/100
= 0.1
Second week = 20%
= 20/100
= 0.2
Total discount = (0.1 + 0.2) / 2
= 0.15
Store B:
25%
= 25/100
= 0.25
Therefore, the store which offers the greater discount is store B.
